I have not had the chance to read my way through this giant thread. But I'm wondering something, since a lot of people say water changes ramp up the problem. Has anyone collected data on mixes vs natural sea water? I'm wondering if some (or most) salt mixes may have an abundance of certain elements the dinos love that are mostly lower or quickly dissipate in the wild? Something you learn about plant hydroponics is that the plants will eat some elements until it kills them, and others will build up because the plants eat much less of them. So over time the situation gets worse and worse. Even changing the nutrient solution only helps you so much. In a closed system (either hydroponic or aquarium) many of the natural checks and balances are absent.
